TYNG-IN IIACHIN E.

To @ZZ fic/wm t may vconcer/n.:

Be it known that l, HUGH l). EANns, a citizen of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented cer tain new and useful Improvements `in Tying-In Machines, of which the following is a specification. Y f

My invention relates toanimprovement in tying-in machines v The object 6ft-he present `invention is to providea greatly simplified machine for automatically selecting threads and tying them together. Another object is to provide a. machine of this character which will include a minimum number of co-operating elements which will not easily get out of order, which can be made and assembled andthe entire machine produced at a greatly reduced expense as compared with others hitherto employed for the same work.

Another object is to provide a machine 'which will accurately select and tie the threads as they are successively separated and presented to the tying mechanism.

This invention includes mechanism whichl automatically moves forward step by stepA in accordance with the size of the threads to be tied, and a'tying mechani'sm which receives the threads and ties them together.

The invention further consists in details and co-operative parts that will be fully hereinafter described and claimed.

A, represents the bed of they machine, mounted on legs 1, which are braced apart by the rods 2.

The threads or yarn 3, 3f, are combed over a rack consisting of plates a held by'bolts 5 on opposite sides ofthe bed ofthe machine. The threads 3 .are taken from the upper rollers 6, and threads `3 from the lower roller 6, and they are carriedacross to the lrolls 7 and 7. respectively, thus making two rows of threads, onek above another across ythe width of the racks. The upperthreads are held` down by the kbars Sand 9, and the lower rows of threads are held down infa lower plane by the bars, 10and 11 as viewed yin'lig. 8. These bars 8 andA 9, and 10 and 11, may be held in place under suitable vtensionby the wing-nuts 12 on the threaded bolts 13, as viewed in Figs. 3 and 12.

In this way, the-required tension is given the threads or yarn, and furthermore inthis way they are held in orderly and properly separated arrangement for successive selecvtion in pairs bythe selector and subsequent tying by the knotter, as will be fully eX- plained. L

A. carriage "14 has parallel beveled opposite edges 15, which are itted .to vslide in correspondingly-shaped grooves 16 in the inner walls ofthe sides of the plates f1, as shown in Figs. 8 and 11. On this carriage 141-, the various working parts of the tyingin mechanismare carried.-

A selector 17 shown in4 Figs. 1, 7, 9,' 1() and 20 is carried on the outer end of an arm 18, which latter is bolted vto the siderof a slide 19, (see Figs. 9 and 20).V This slide 19 is guided by,'and held in sliding relation with, `the slide-frame 20 by means of ball-V bearae's .21 (ses ,Fgll). AThe selector is arranged and adapted to be reciprocated in any approved manner, for instance through the connecting-rod 22 pivotallyconnected at one end to the slide, and at theother to the wrist-'pin 23 on the disk 24 keyed on the rotary shaft 25. This shaft 25 is driven at a slow rateof speed by a large gear-wheel 26 keyed thereon, which receives its motion through a pinion 27 on the shaft 28. A worm-gear 29 keyed on the shaft 28 is driven by the worm 30 directly from `the motor 31; and this motor 3l is conveniently mounted on a bracket 32 bolted to, and depending from, the lower side ofthe slide 14, as shown in Fig. 4.

The selector 17 has two jaws 33 which have inwardly-converging forward edges forming a mouth, and between them the tongue 34 is located, vleaving a space on either Vside to receive the upper `and lower threads 3 and 3 respectively, as viewed in enlarged form and in section in Fig. 7.

As the selector moves forward, the tongue 34 enters between the two horizontally disposed layers or rows Vot threads or yarn, keeping them apart, and receiving a thread both above and below the tongue, as-shown in Figs. 7 and 20. As the selector moves fom/ard, several `threads enter `the spaces in the throat of the selector between 1the tongue and the upper and lower edge. Tt is importantthat only one thread of each row be selected at a time. This may `be accomplished in different ways. As a simple method of selecting ythese two threads, `the selector-linger 35 is employed, as shown in enlarged detail in Fig. 7. This-finger is connected to a barby-pivot-pin 37, from which pointas a center it may be Yadjusted to the right position. This b ar 36 with the finger is controlled andactuated by a rocking-lever 3 8 fulcrumed `on -a stud 39 on the side ofthe selector 17,'the 'forward end of the rocker-lever being connected with the bar 36 by a pivot-pin 40,7andthe opposite end being free but provided with an inwardly-projecting stud 4l of more or less triangular form (seeFigs. 9 `and l0). This stud vv4l is in position to be engaged'or passed by the bevel-endedcam 42, according to circumstances. The beVeLende-d cani 42 is a grooved cam pivoted by the pin l43 to a wish-bone slide 44, which has limited sliding connection with the slide l9by reason of the screws 45 extending through the slots 46. This wish-bone slide being held in con tact with a cam 47 on the shaft 25 by ka spring 48 secured to the slide '1.9 and the wish-bone slide. 44 as shown in Fig. *9, and with each rotation ofthe ca1n47 in 4contact with the adjacentend of Vthe wish-bone Aslide the latter -is forced *forward Y`a distance equivalent lto -thle length ofthe slots 45.`

The position ofthefbevetendedcam 42 `is rnormally `as shown in 9, when@ it;

point.

drops by gravity, and in which position it would clear the triangular stud 4l, which would mean the slide-bar 36 andthe linger would remain stationary. A trip 49 is pivoted on the forward end of a slide-rod 50 crossing ,the rear end of the spaces between the jawsand the tongue as shown in Figs. 9 and l0, and a delicate spring 5l normally forces this trip forward as shown in Fig. 9; but, with the forward movement of the selector, the tension of the first two threads 3 ant 3 is suiiicient to press equally on both ends of the trip 49, and to slide the rod 50 backward in the direction indicated by the arrow in Fig. l0, and, through the instrumentality of the bellscrank lever 52 pivoted at 53 on the bar 18, striking the pin 54 on the bevel-ended cam 42 to lift the point of the latter into the plane of the triangular stud 4l, so that as the wislr bone slide 44 moves forward, the bevel face of this `cam rides over the upper-surface of the stud, thereby rocking the end of the lever 38, upon which the stud is located, down, and the opposite end with -the bar 3G and the .linger 35 up, to canse the finger to segregate the two adjacent threads 3 and 3 from the rest.

Should a single thread entera set of' two on one side of the tongue 34, instead of both sides, the trip 49 would merely tilt on its pivot without forcing the rod 50 back, as indicated by the arrow, and consequently the remaining parts would retain their normal position as shown in Fig. 9, and the selector would not function, or, in other words, the .finger 35 would not move. This is important, as two threads are essential to the accomplishment of the` purposes of the machine. A stop 55 beneath the bellcrank lever limits its downward movement, and a spring' 56 returns the lever 38 and the connected parts to their normalposition.

The position of the point of the selectorfinger is adjusted to the size of the thread or yarn, to insure against picking more than two threads, by means of the set-screw 56 operating' in the elliptical countersunk slot 57 in the bar 36, as shown in Fig. 7.

Immediately upon the threads 3 `and 3 beingipicked `out from the other threads and held by the selector-finger 35, the selector is drawn back into the tension device, and within reach of the knotter as shown in Fig.` 20, preparatory to the threads being tied together. VJhen thus drawn, the knife-blade 58 is caused to shear against the Vside of the selector as shown in Fig. 20,

thereby cutting thethreads 3 and 3 at that The knife-blade 58 is pivotally mounted on a stud 59, and it is actuated by the stem G() striking thestub 6l on the carriage 14. The knife-blade is normally held as shown in Fig. 20 aga-inst the pin G3 by the spring (i2, and the lug; 6.4 0n .the

rasser/se stem by striking a pin on the knife-blade forces the latter upwardly, and aftery the selector is moved still further back, the stem 60 drags over the stub 61, and the spring 62 returns the knife-blade to vthe position shown in Fig. 20, whereait is stopped by the pin 68, and the stem 60 isleft free to ride over the top of the stub 61 when theselector again moves forward to choose the next two threads. j

The tension device is composed of a plate 66 having an inclined forward edge up and over which the threads ride as shovedback by the selector, land as shown in Fig. 20, until caught and temporarily held by the spring tension 67 before the threads are cut by the blade 58,' and while being tied togetherand untilthe threads are again severed at any point by the knotftyer at'the completion `of the. tying of the knot.

The tension device'and the knetter are carried on ahead 68, the stem 69 ofwhich extends through the biuihingsl 7 0 screwed in opposite directions through a hole 71 in the carriage as shown in Fig. 6, cups 72 being formed at the ends of the bushings for the ball-bearings 7 3. A rocking' pinion 74@ keyed on the stem 69 is engaged by the teeth of the rack-bar 75, andthe stem 76 of this rack-bar has sliding connection `-with the slide 77, whichlatter isguided in its movements in the slide-frame 78 by ball-bearings 79. Thisxslide is operated by connectingrod 80V extending from the crank-disk 81 keyed on the shaft' 25.

yThe knotter is carried on the head`68. A post pro`ects upwardly from thehead 66, and is divided or slotted at its upper end to form a divided bill 83, as viewed in Figs. 13 to 18, and a tying-hook Se is fitted in the space between the parts of the bill, between which it is guided as it swings upon its pivot 85.

`Vilhile the threads 3 and 3 are being held by thetension device in the position shown in Figs. 13 and 20, the head 68 is given about a three-quarters revolution to the point shownin Fig. 15, forming a loop in the threads around the bill, and into a notch 86 in the side of the tying hook with the threads crossed as shown in Fig. 17 -where it is retained temporarily. f

The severing of the threads by the knifeblade 58 is timed to occur just in advance of the rotation of the head 68, and by furnishing the slack required to form the loop 87 and the cross in the threads at the point 88 (as shown enlarged in Fig. 17) the tension device 67 keeps the threads taut and permits them to rpull part way therethrough as required to form theknot.

A portion of the `threads thus held taut by the knotter and the tension device is in the4 direct path of the upward movement of P a thread-guide 89 ony the outer end of the thread-guide arm 90, as shown iirFigs. 141,

15 and 1.7. This thread-guide arm pivotally supported to one side of the head 63 by a screw v91, and a stud 92 projects from its side in the' direct pathvof a plunger 93 projecting 77, with which it is adjustably connected by aV set-screw 941 extending` through the slot 95.

f By mately completed its three-quarters rotation in the formation-of the loop, has moved forward in the direction indi-y cated by the arrow in Fig. 15, and its further movement from this point against theV fromthe forward end of the slide the time the head 68l has approxi* the plunger 98 stud 92 causes the thread-guide arm-"90 to i swingen itsV axis 91 in thearc of a circle. The thread-guide 89 being immediately below the threads lifts and carries them over in a reversedirection (as shown in Fig. 17)

drawing asmuch of the threads as required through the tension'device, forming a further cross kin the threads overr the loop. As

the thread-guide arm continuesfon to the position ther forward movement of the plunger 93, a cam 96l on the `inner face of the threadguide 1 arm' by swinging against lthe bprojection 97 just below the notch 86'forces the knotter-hook 84E to the positionshown in Fig. 18, .which causes the outer end 98 of the hook 84- to gather in the threads laid shown in Fig. 16, due to the furbetween the hook and thefingers'of the bill j by thethread-guide 89 (see Fig. .17 iy and by the shearing action of the sharp edge98 of the hook against the corresponding edge fingers of the Abill 83 beneath the loop 87 formed in the threads has stripped the. latter from the knetter by rising still 'further :99 of the bill, to cut the threads and at theL tothe outer end of the bill 8S, asshown in l Fig. 18. rlhis stripper is connected by links 101 and 102 to a lever 105 fulcrumed at 10.41

which is lifted by' the greove106 on the back of the thread-guide.arm 90 striking the pin 105 on the lever 10S, as shown in Fig. 16. As this lever 103 continues to rise, a shoulder 10'( thereon (see Fig. 1.53) by lifting the stem 108 projecting'froin the shaft 109 in its path (see Figs.' 13, 16 and 19) causes the part round shaft 109 to rock from the position shown in Fig. 19, in which a portion of the yspring tension 67 rests upon the flat face of the shaft to bring the rounded surface of thek shaft against the tension device, whereby to raise the latter and release the bits of thread held bythe tension after the severing of the thread on both sides thereoff, These bits are blown out by a fan orV ,blow-pipe; (not shown) as fast as they are released.l v

A spring-110 returns ,the parts to normal,

as shown in F 13, 11- and 15'. i A springl 111 sleeved upon the rod 75 allows tor the difference in motion Vbetween the rack-bar and the slide 77.

Vvith each reciprocation ot the selector 17, there is a progressive movement ofthe carriage 14 adjusted to and corresponding to the size of the thread or yarn being tied. While this may be accomplished in various ways, the means illustrated is well adapted to the purpose. A stub-shaft 112 rotatably supported by the `bearings in the bracket llbolted to one-.side of the carriage 1stas shown in Figs. 3, .11, 5, 11 and 20. 0n this stub-shaft 112, a wormwheel 114i is keyed, and this worm engages and turns in contact with the teeth 115 on the bar 116 extending practically the entire length of the machine as shown in Fig. 2. On the hub yof this worm, ratchetteeth 117 are for-med, and a gravity pawl 118 engages these teeth. This pawl is pivoted as at 120 to a lever 121, which latter in turn is pivoted by the pin 122 at the outer end of the bracket 113. The opposite end of the lever `121 has a fork `123 which straddles a pin 124 on the inner end of the lever 125, which latter is pivoted to the side ot the trame'20 by screw 126, `and normally held in an elevated position* by the tension of spring 127 (seeFigs. 5 and 20).

The inner end of lever carries roller 128 and this projects through a slot 129 in the side of the trame 20, in the path of a V-shaped cam 130 carried by the slide 19. The cam 130 is adjustable up and down by a set-screw 131 to. give the required turn to the worm. This adjustment of the V- shaped cam 130 is required to determine and regulate the exact distance ot the progressive, step by step, forward movement ot the carriage with respect to the thickness ot the yarn or thread being' operated upon. lith each reciprocation of the slide 19, the lever 125 is rocked, and with it the lever 121.; and through a Ypawl 118 operating on the ratchet-teeth 117, the worm is turned just the required distance to bring the carriage forward to the right position for the selector on moving forward to gather in the first two adjacent threads 'for the knetter.

As a preliminary to the starting of the machine with a new rack full of yarn or threads, it is necessary to slide the entire carriage back by hand. Provision is made tor this through the shifting of' the toothed bar 106 bodily from the path of the worin 11st. The rack 116 is mounted upon an eccentric 1232 at each end of the rack. These eccentrica are on vertically disposed bearings Levers 12E-1 and .135 are secured to these eccentrics, as shown in `Figs. 2, 5 and 11, the lever 135 .beingla hand-lever, and these levers are connected by a rod 136 `(see Figs. 2, e and llt) so that when the operator wishes to push the carriage 14; back, or return it to `normal (as illustrated in 2), he siinplyturns the hand-lever 135 to oneside, thereby shitting the toothed bar 116 laterally from end to end through the medium ofthe eccentrics away from the worm 1114.v Then .the carriage is slid by hand vba-ck to the starting-point, and the bar 11G is returned to the normal shown in Figs. 2,15, 111 and`20 by swinging the hand-lever back tothe position illus trated in fFigs. 2 and 5which1brings the worm 114- again into mesh with the teeth of the bar A116. A

The movements are all properly timed. TVith each complete forward and backward stroke of the selector the entire carriage moves `forward the Width of the yarn or thread, so that when the selector .reaches its extreme A:forward stroke, it is in `position to receive 4the two nearest threads inthe position shown in Fig. 7, ready to be gathered in by the selector-finger 35 on lits upward movement. With the `backward stroke, the

4the loop isforined 4about the bill Aand tyingposition Sil V20 threads are brought againsttheknotter, in-

hook, and the knot isformed, the threads are .cut and held until the knot is stripped `from the knotter, whereupon `the severed bits of threads are released by both knotter and tension and blown out of the machine, and the operation is repeated `until the entire rackful ot yarn or threads is tied.
